Can you accurately flow a different gas through a flow control device not calibrated for the same gas?

Quite often, when in the field, it becomes necessary to use another gas through a flow control device such as a flowmeter, flowmeter regulator, or flow gauge regulator. While the flow control device may be safe and compatible for the other gas, the issue often becomes one of accuracy.

What general maintenance should be performed on a regulator and how often?

A regulator (or changeover manifold) can last several years if properly maintained. Regulator maintenance is an important part of maximizing your system performance and extending the service life of your system components.

What is the 1/7 acetylene rule?

Acetylene by nature is an unstable gas that has limitations. The 1/7 rule protects operators from unsafe operating conditions. But what, exactly, does the 1/7 rule say and what effect does it have on acetylene cylinders? This blog entry written by Neal Lembke answers those questions.

What factors go into selecting regulator gauges?

A regulator gauge is a simple device whose sole function is to indicate high and low pressures flowing through the regulator. That doesn't mean all gauges are the same.

Did you know that gas flames produce infrared radiation?

Gas flames produce infrared radiation, which may have a harmful effect on the skin and especially on the eyes. Proper eye protection is vital to prevent permanent retinal damage.

Did you know that a protocol station can extend the life of a regulator?

Sometimes referred to as single station manifolds or regulator mounting stations, a properly installed protocol station can extend the life of a regulator.

Did you know that you can solder an HVAC connection?

Did you know low-temperature tin/silver solders have higher strength and ductility than typical plumbing solders? This makes them suitable for most residential HVAC connections.

What is the difference between Harris silver brazing fluxes and where is each one used?

We get a lot of questions about the differences between the silver brazing fluxes we make and where each one should be used, so we've prepared a short guide that provides the answers.

Why is flux required when brazing brass and not required with copper to copper?

A fluxing agent (or a controlled atmosphere as found in furnace brazing) is required for all brazing and soldering applications. The purpose of the flux is to remove oxides from the base material and to prevent oxidation during the heating process, thus promoting the free flow of the brazing filler metal.

What is the difference between gas welding and braze welding?

Gas welding and braze welding both require skill, patience and an oxy-fuel torch. There are several differences, however, between the two applications that require different techniques and materials.

With a single stage regulator the delivery pressure rises as inlet pressure decreases - why?

Gas regulators are designed to reduce pressure to a usable volume for a specific application. What happens when gas flows into a single stage regulator?

What is the difference between RG45 & RG60 welding wire?

Both are solid wire oxyfuel welding rods, but each has its own distinct characteristics.

By Bob Henson

What is solidus and liquidus and why is it important to brazing?

If you look at a list of brazing filler metals you’ll note many compositions and a variety of melting temperatures. The melting characteristics of brazing filler metal are an important aspect in filler metal selection. Here's a brief outline of how alloys melt and the way to use this information to make the best selection.

Can titanium be cut with an oxy-fuel torch?

Titanium can be cut with an oxy-fuel torch as long as you take certain precautions to protect yourself and your work area.

Why do cylinder valves have different thread types?

It is required in the U.S. by OSHA and the Compressed Gas Association (CGA) that cylinder valves be designed differently to prevent interchangeability with gas systems and equipment. This is one of the most important safety practices in the gas industry.

What metals can be brazed?

Many different types of metals can be brazed. Copper, and copper based materials like brass and bronze, are typically brazed with copper phosphorus silver alloys also known as American Welding Society (AWS) BCuP filler metals.
